I have a 15 AMP breaker that will not stay on. Shut off lights, went to bed as usual and in the morning the lights would not come on. I inspected the breaker panel and found that circuit was tripped. When I tried to flip it back on, it lasted less than a second with a sort of "bzzzz pop" sound. Same results every time I try to flip it back on - seemed like a short to me.
This breaker covers the overhead lighting (13 recessed flood lights) for 2 rooms and vanity lighting (4 LED bulbs) and 2 outlets (1 is GFCI) in a bathroom. There is a light switch in the bathroom, a light switch in one room and a dual switch in the other (one for each room). I figured I'd start ruling out components one by one.
In order to troubleshoot, I first removed all the bulbs just in case there was a bad ballast causing an issue - no change. I then removed the leads on all the outlets and light switches and tried again - no change. I then swapped out the breaker in the main panel - no change. I crawled into the attic and didn't see any damage (though a lot of the wiring is not easy to get to, I saw no evidence of animals chewing through anything). Is there anything I'm missing that I could look at?
